Out of all the toys I've tried, my favourites have all been Tantus... so Tantus all the way for me! (now if only they made smaller toys in the O2 line, that'd be swell... 1,5 inches in diameter is still pretty big for me. :/)

I've read a lot of positive comments about the quality of Tantus toys but I am not a fan of their designs.

Update: I am loving the texture O2 silicone. I am yet to try VixSkin, so for now Tantus is my number 1 for silicone dildos. I will definitely be buying more Tantus in the future, however I still don't like most of their designs.
